Duplex ultrasound

Duplex ultrasound ndiyeso kuti muwone momwe magazi amayendera kudzera mumitsempha ndi mitsempha yanu.

Duplex ultrasound ikuphatikiza:

• Chikhalidwe cha ultrasound: Izi zimagwiritsa ntchito mafunde omveka omwe amatulutsa mitsempha yamagazi kuti apange zithunzi.
• Doppler ultrasound: Izi zimalemba mafunde amawu akuwonetsa zinthu zosuntha, monga magazi, kuti ayese kuthamanga kwake ndi zina momwe zimayendera.

Pali mitundu yosiyanasiyana ya mayeso a duplex ultrasound. Ena mwa iwo ndi awa:

• Matenda osokoneza bongo komanso am'mimba m'mimba. Kuyesaku kumayang'ana mitsempha yamagazi ndi kuthamanga kwa magazi m'mimba.
• Carotid duplex ultrasound imayang'ana mitsempha ya carotid m'khosi.
• Duplex ultrasound ya malekezero amayang'ana mikono kapena miyendo.
• Renal duplex ultrasound imayesa impso ndi mitsempha yawo yamagazi.

Mungafunike kuvala chovala chamankhwala. Mudzagona pansi patebulo, ndipo katswiri wa ultrasound adzafalitsa gel osakaniza m'dera lomwe likuyesedwa. Gel osakaniza amathandizira mafunde amawu kulowa m'matumba anu.

Wendo, wotchedwa transducer, amasunthidwa mdera lomwe likuyesedwa. Wendo uwu umatumiza mafunde akumveka. Kompyutala imayeza momwe mafunde amawu amabwerera mmbuyo, ndikusintha mafundewo kukhala zithunzi. Doppler imapanga phokoso "swishing", lomwe ndi phokoso lamagazi anu loyenda m'mitsempha ndi m'mitsempha.

Muyenera kukhala chete pakuyesa. Mutha kupemphedwa kuti mugone m'malo osiyanasiyana, kapena kuti mupume kwambiri ndikugwira.

Nthawi zina pa duplex ultrasound ya miyendo, wothandizira zaumoyo amatha kuwerengera chikhomo cha bracheal (ABI). Muyenera kuvala zomangira zamagazi m'manja ndi m'miyendo pachiyesochi.

Nambala ya ABI imapezeka pogawa kuthamanga kwa magazi kumapazi ndi kuthamanga kwa magazi pamnkono. Mtengo wa 0,9 kapena wokulirapo ndi wabwinobwino.

Nthawi zambiri, sipakhala kukonzekera mayesowa.

Ngati mukukhala ndi ultrasound m'mimba mwanu, mungafunsidwe kuti musadye kapena kumwa pakati pausiku. Uzani munthu amene akuyesa mayeso a ultrasound ngati mukumwa mankhwala aliwonse, monga opopera magazi. Izi zingakhudze zotsatira za mayeso.

Mutha kumva kupsinjika ngati chingwe chikuyenda mthupi lanu, koma palibe vuto nthawi zambiri.

Duplex ultrasound imatha kuwonetsa momwe magazi amayendera kumagulu ambiri amthupi. Ikhozanso kudziwa kutalika kwa mtsempha wamagazi ndikuwonetsa zotchinga zilizonse. Kuyesaku ndi njira yocheperako kuposa arteriography ndi venography.

Duplex ultrasound itha kuthandizira kuzindikira izi:

• Mitsempha ya m'mimba
• Kutsekemera kwamkati
• Kuundana kwamagazi
• Matenda obwera chifukwa cha Carotid (Onani: Carotid duplex)
• Matenda a impso
• Mitsempha ya Varicose
• Kulephera kwamphamvu

Aimpso duplex ultrasound itha kugwiritsidwanso ntchito pambuyo pochita opaleshoni. Izi zikuwonetsa momwe impso yatsopano ikugwirira ntchito.

Zotsatira zabwinobwino ndimayendedwe abwinobwino amitsempha m'mitsempha ndi m'mitsempha. Pali kuthamanga kwa magazi koyenera ndipo palibe chisonyezo chakuchepa kapena kutsekeka kwa chotengera chamagazi.

Zotsatira zosazolowereka zimadalira dera lomwe mukufufuzalo. Zotsatira zosazolowereka zitha kukhala chifukwa choundana wamagazi kapena zolembera mumtsuko wamagazi.

Palibe zowopsa.

Kusuta kungasinthe zotsatira za ultrasound ya mikono ndi miyendo. Izi zimachitika chifukwa chikonga chimatha kupangitsa kuti mitsempha igwe.

Mitsempha ya ultrasound; Zozungulira mtima ultrasound

• Angioplasty ndi stent mayikidwe - zotumphukira mitsempha - kutulutsa
• Mitsempha yakuya - kutulutsa

• Kuyesa kwa duplex / doppler ultrasound
